[HELP] HTTP Proxy - Host CaSe seNsitiVe?

[flash600]

Hello,

if the hostname in “Reverse Proxy / HTTP Proxy” contains capital letters, the proxy redirection does not work, I get “Error 404 Target Host Not Found”.
I have tested with:
SIO-APPP.domain.com => does not work,
but if I add an alias with lower case letters, e.g.
sio-appp.domain.com => then it works

My question: is this “by design” or is this a bug?

Thank you very much!

Technically there are no limitations or standards that limits the host case-sensitivity in reverse proxy, but after some research I think we shd stick with what the DNS standard (RFC 3986 § 3.2.2) is, which is by design, case insensitive.
